Product Description
The product is an intelligent inverter with built-in charge controller designed for large
photovoltaic power generations.
Its built-in controlier can realize charge management for a battery pack by multiple solar arrays
to improve charge efficiency and lite of the battery pack.
Thanks to the DSP control basek on SPWM high-frequency carier technology and IGBT power
device, it can control the output operation parameters accurately to provide a high quality and
reiable pure sine wave AC power supply for precision equipment.
It is widely applied to large solar power generation occasions inaluding families, schools, public
lighting, industrial and mining enterprises, frontier defense, sea islands,pasturingareas, ete.
